Voices in Your Head: The Role Hair Can Play in Forensic Toxicology

As efficient as it may be, hair can be quite a challenge in forensic labs, particularly because there are so many factors that affect the success rate of of obtaining a DNA sample. For instance, the chemicals that have been mixed into the hair as a result of dyeing can alter the cuticles, and can even contribute to the degradation of hair DNA.

An efficient forensic toxicologist, like one from Environmental Diseases, works with many body samples like hair, skin, blood, and other bodily fluids so as to render an accurate opinion on the diseases, poisons, drug use or other medical conditions. These experts are often called upon by courts to stand as witnesses for criminal cases.
